1996–2020
Minor League Baseball operated with six classes (Triple-A, Double-A, Class A-Advanced, Class A, Class A Short Season, and Rookie) from 1996 to 2020. The Rookie level consisted of domestic and foreign circuits.

2021–present
The current structure of Minor League Baseball is the result of an overall contraction of the system beginning with the 2021 season. Class A was reduced to two levels: High-A and Low-A. Low-A was reclassified as Single-A in 2022.
